Manuscript

A manuscript is a recording of information that has been manually created by someone or some people, such as a hand-written letter, as opposed to being printed or reproduced some other way. The term may also be used for information that is hand-recorded in other ways than writing, for example inscriptions that are chiselled upon a hard material or scratched (the original meaning of graffiti) as with a knife point in plaster or with a stylus on a waxed tablet, (the way Romans made notes), or are in cuneiform writing, impressed with a pointed stylus in a flat tablet of unbaked clay. The word manuscript is derived from the Latin manu scriptum, literally "written by hand."

In publishing and academic contexts, a "manuscript" is the text submitted to the publisher or printer in preparation for publication, usually as a typescript prepared on a typewriter, or today, a printout from a PC, prepared in manuscript format.

Originally, all books were in manuscript form. In China, and later other parts of East Asia, Woodblock printing was used for books from about the seventh century. The earliest dated example is the Diamond Sutra of 868. In the Islamic world and the West, all books were in manuscript until the introduction of movable type printing in about 1450. Manuscript copying of books continued for a least a century, as printing remained expensive. Private or government documents remained hand-written until the invention of the typewriter in the late nineteenth century. Because of the likelihood of errors being introduced each time a manuscript was copied, the filiation of different version of the same text is a fundamental part of the study and criticism of all texts that have been transmitted in manuscript.

In Southeast Asia, in the first millennium, documents of sufficiently great importance were inscribed on soft metallic sheets such as copperplate, softened by refiner's fire and inscribed with a metal stylus. In the Philippines, for example, as early as 900, specimen documents were not inscribed by stylus, but were punched much like the style of today's dot-matrix printers. This type of document was rare compared to the usual leaves and bamboo staves that were inscribed. However, neither the leaves nor paper were as durable as the metal document in the hot, humid climate. In Burma, the kammavaca, buddhist manuscripts, were inscribed on brass, copper or ivory sheets, and even on discarded monk robes folded and lacquered. In Italy some important Etruscan texts were similarly inscribed on thin gold plates: similar sheets have been discovered in Bulgaria. Technically, these are all inscriptions rather than manuscripts.

Manuscripts are not defined by their contents, which may combine writing with mathematical calculations, maps, explanatory figures or illustrations. Manuscripts may be in the form of scrolls or in book form, or codex format. Illuminated manuscripts are enriched with pictures, border decorations, elaborately engrossed initial letters or full-page illustrations.
